Aha, okay. So it basically needs special config to work, and
complaining that it does not boot noapic is not helpful.

Yes, right, this was Linux's fault.

Actually s2ram used to work for quite long time... with video needing
userspace hacks. Just some compaq evos are problematic :-) [acpi
problems, and firmware has definitely some problems, too]. Thinkpads
tend to be rather good. (suspend.sf.net has video parts.)
